What 10mm/40 caliber cartridges are available?

[TPAshooter7.62]

All:
I've been thinking about possible options to chamber a 40 caliber/10mm revolver to a custom cartridge. So far, I have following:

40 S&W
10mm auto
10mm magnum
401 Herter's Powermag
38-40 (38 WCF)
41 Long Colt
400 Corbon

So, did I miss anything? Thanks. TPA.

.41 Long Colt is a .406 to .408 bullet.

DEFINE " custom cartridge " as you use it here, please.

PS: you missed several.

Not originally designed or not originally used but the cylinder reworked to be used with the revolver. I forgot to include 401 GNR. So, what DID I miss? Thanks. TPA.

JD Jones came up with a couple. Using both the .44Mag (.40-44 Woodswalker) and .454 (.40-454JDJ) cases necked down. It's tough to get commercial jacketed pistol bullets to stay together at those velocities though. I don't know if either is applicable to revolver use. Pressures are in the 60,000psi range.

.41Colt (Short and Long) actually used a .401" heel based bullet or a .386" inside lubed hollow-based bullet and the same .400" bore as the rest.

I designed my 401 Bobcats back in 1994 (3rd and 4th from the left):

Forgot about your .401 Lee!

There's also the old 400 Colt Magnum prototype from '63-'64. I was lucky enough to acquire two:

What was the case length on that one again?

 

[Lee Martin]

1.275". It's virtually a 401 Powermag. Colt used unstamped 30-30 hulls to form the prototypes. The final markings were "400 W-W"

Cool, I'm still thinking seriously about doing something like that with an Old Model .357 converted to .38-40 with another cylinder in a straight-wall like the .401.

Neat. I have a stainless Talo 44 that's gonna be converted to my short 401 Bobcat this winter (ie, the 1.29" version).
